Article Abstract
We have demonstrated heretofore unattained distance precision of 0.14 pm (2 pm) incremental and 14 nm (2.9 μm) absolute in a resonant (nonresonant) interferometer at an averaging time of 1 s, using inexpensive telecommunications diode lasers. We have controlled the main source of error, that due to spurious reflection and the resulting amplitude modulation. In the resonant interferometer, absolute distance precision is well under λ/6. Therefore, after an interruption, an absolute distance measurement can be used to return to the same interferometer order.

Natural polyreactive antibodies achieve enhanced avidity through heterogeneous ligand binding. However, engineering synthetic heteroligation systems with precise control over recognition motif orientation and distance remains challenging. Here, a DNA framework-based strategy is presented to program heterotypic binding by spatially organizing bivalent aptamers targeting platelet-derived growth factor-BB (PDGF-BB).

Achieving quantitative control over interlayer spacing in multilayer two-dimensional (2D) supramolecular organic frameworks (SOFs) remains a fundamental challenge. Here, we report a molecular pillar engineering strategy enabling programmable vertical expansion of bilayer architectures. By designing elongated bipyridine pillars L2/L3 (3.

Purpose: Pelvic ring fractures involving the iliopubic rami can cause functional impairment. Percutaneous retrograde fixation is a less invasive procedure when compared to traditional open approaches, however precise anatomical knowledge is crucial for safe screw placement. This study aims to describe the morphology of the iliopubic rami, define a safety corridor for percutaneous screw fixation, specially focusing on the relationships between the iliopubic rami and neurovascular structures.

Accurate attribution of the areas and populations impacted by climate-related events often relies on linear distance-based methods, where the study unit is assigned temperature data to the closest weather station. We developed a novel method and data pipeline that provides a grid-based measure of exposure to extreme heat and cold events called Grid EXposure (, enabling linkage to individual-level human health data at different spatial scales. GridEX automates the gathering of station-based climatological data and provides estimates of apparent temperature, offering a more comprehensive representation of human thermal comfort and perceived temperature.
